Fork PRs (e.g. #845) run without OPENAI_API_KEY and without local
speech models, so global-setup.ts:420 threw and blew up the entire
Playwright job before any test could run.
Soften the gate: when neither path is available, warn and run with
dictation/voice disabled. Daemon already honors PASEO_DICTATION_ENABLED=0
and PASEO_VOICE_MODE_ENABLED=0. No spec currently exercises dictation,
so nothing else needs to change; future dictation tests should gate on
PASEO_DICTATION_ENABLED.
